'V 'STHETCHNG reame) YApplication led J'anuary AMy invention relates to a device for holdingor stretching skins or pelts for drying,

curing, or otherwise treating the same.

My invention will be best understood from the'follofwing desoriptionwhen read in light of the accompanying Vdrawing of a specific embodiment. of myinvention selected for i illustrative purposes, while the scope of'my separation of they' side arms the side arm invention-will be more particularly out'in thel appended claims. y

In the drawing y l Fig. 1 vis an elevation of a -device con. structed according to my invention; ,ll Y Fig. 2 is a side view according to Fig.. 1'; VFig. 3 is a section on'the line 3-3101` Fig. 1;and ,V1 i

Figs. 4 and 5 are1respectively'sectionson f the lines 4-4 and 5-15'o-Fig13.

Referrngto the drawing and ltothe preferred embodiment of my invention I have shown a Vf-shaped frame whichconveniently is made of al resilient rodv bent to Vform the opposite side arms land 3, which arms pointed are movable Vtoward and away from each other about the portionr'forming the apexv of the frame. For 'limiting the extent of 9 J at its vlower end is bent at Yright angles to form' a side arm connecting portion 7 which extends through an eye 9 formed at'the end of the side arml; the outer end of the portion 7 being bent upwardly to form a stop 11 coasting with the eye 9.

` For holding the side arms 1 and 3' apart and for providing a means tov whichthe lower end of the skin or pelt may be attached when the frame is in use I provide a cross bar 13 conveniently made of a'length of, flat bar stock which at opposite ends has Aformed therein slots 15 through which the side arms 1 and 3 extend. At each endlthe cross bar has pivoted thereto at 17 vthe endv of a side arm engaging member 19, each ,member 19 being formed'on one side thereof r with notches 21 adapted to engagethe adjacent side arm.r` As indicatedv in Fig. 1 the side arms 1 and 3 on their -inner edgesare formed with a series `of spacednotches 23 which yengage the sides of the notches 21 of f the members 19 Jfor holding the .cross'bar in Y adjusted position lengthwise oi" the side armsf Y ,For gripping the Skinl or pelt to the `crossj bar I provide a bar 25 which" as shown is of the same thickness as Vthe stock forming the 17, 41925. serial No. anse/1 y'cross vThebarzl2r5 adjacent VoneV end `,connected to'thebar .13 means ofthe links 1 27 which at opposite-ends are pivoted at 29 .Y

and 31to the bar 25 and bar'13 respectively, f

thelength of the links being suchY as to normally space vthe'opposed edgesV of the bars .y

Althoughl have'described for purposes i' yof illustration one speciiic embodiment Vof Y my invention it is to be understood that I amV not limited Vthereby Ato its particular mechanical details,`but that within the scope of my invention 'wide deviations may be made therefrom without departing fromthe spirit of my invention;
